Empirical Design Considerations for Industrial Centrifugal Compressors

Abstract EN

Computational Fluid Dynamics (CFD) has been extensively used in centrifugal compressor design.

CFD provides further optimisation opportunities for the compressor design rather than designing the centrifugal compressor.

The experience-based design process still plays an important role for new compressor developments.

The wide variety of design subjects represents a very complex design world for centrifugal compressor designers.

Therefore, some basic information for centrifugal design is still very important.

The impeller is the key part of the centrifugal stage.

Designing a highly efficiency impeller with a wide operation range can ensure overall stage design success.

This paper provides some empirical information for designing industrial centrifugal compressors with a focus on the impeller.

A ported shroud compressor basic design guideline is also discussed for improving the compressor range.
